MIXING LIQUIDS O33- EJEMILIQUIDS.

Application filed March 23, 1921. Serial No; i-54,955.

To all air/lam it viz r2; concern:

Be it known that i'JILHiJLiii Manes, a tish subject, residing at 72, Cullinan lhuldings, Simmonds Street, Johannesburg, 5 'iransvaal Province oi the Union or? South -"riirica, has invented certain new and useful improvements in Mining Liquids or ei'i'iiliouids, which the following is a specification.

The present invention has reference to adding; one liquid or semi-liquid to another in definite proportions; and in tl1'e.pa'rticr1- la; ihodiinent hereafter described it is applied to the liming of sugar juice for continually adding 2 small proportion of lime in admixture withwater to a stream of juice.

The purpose oi the invention is to enable the proportions of the two liquids to be maintained constant irrespective of variation of the volume of the liquids treated. Another object is to enable the proportion to be readily varied if desired. i-rnother objcct is to provide an apparatus specially adapted for adding. with exactness, a very small proportion oi one liquid to a large proportion of the other.

The invention is illustrated in the acconipanying drawings in which F I shows the general arrangement, and

H is an enlarged dctaii view of one of the vanes oi? the bucket wheel.

1 indicates a launder delivering sulphured sugar juice. fit the end of said launder is an undershot bucket wheel 2 which is turned by the juice flowing from the launder.

The invention aims to make the revolutions of the wheel 2 closely proportional to the flow of juice, and with that object means are provided to prevent leakage between the wheel and its casing 3 and also to ensure that the buckets 4 are always full.

The drawing shows the end surfaces of the nave 5 formed for this purpose with annular packing grooves 6, which in the well known manner inhibit the flow oi? liquid between themselves, and the adjacent surfaces of the casing 3. Similarly longitudinal packing grooves 7 are formed on the edges 8 and 9 of the blades.

To ensure the buckets being filled there is provided in the launder 1 a float 10. Said float is attachedrto a lever 11 carrying a brake block 12 which cooperates with a brake drum 13 fast with the wheel 2. Before the juice in the launder falls to such level as would cause the buckets l of they vhcei not to fill completely, the brake comes into operation and holds the wheel from revolving until the How of juice raises the levelin the intruder 1 to the proper point.

From the bucket wheel the juice is deliv ered to the box 14: wherein the lime is added juice and of washing the buckets in the juice to keep them clear 01": lime deposit which would tend to upset the balance of the conveyor, such balance being of importance for the reason stated hereafter. The part of the box into which the conveyor 15 dips, is shut off from the main portion of the box by a battle 1'? so that the limed juice does not again mingle with the untreated juice. The limed juice passes away by the outlet 18.

The bucket wheel 52 and the sprocket 19 oil the conveyor are connected for uniform movement by mechanism including the belt 20, bevel 21, the friction wheel 22 and the friction disc 21% Fast with the sprocket 19 and in driving; engagement with the friction wheel it is desirable not to impose any substantial work on the bucket wheel 2 in order that the head above it may be kept low and leakage past it and friction minimized. Consequently the lime supply tank 16 is raised and the conveyor 15 is arranged substantaf y to drive itself by the preponderance oi: the weight of the descending full buckets a; over the eu'ipty ascending buckets 7 the connections 20, ill, and serving; thus simply to maintain uni'tormity between the motions of the bucket wheel and the conve vor.

The conveyor buckets 9A: are jointed to the chain 25 at 26 so that they can tilt freely thereon; Trey are so weighted that normally they assume and maintain the carrying; position as indicated at a". As they leave the bottom of the liming b05114: they meeta ramp 2'? which tilts them to discharge their lime contents and maintains them tilted until they "emerge from the sugar juice.

the apparatus is Working.

Advantage is taken of the fact that the revolutions of the bucket wheel closely correspond to the volume of:juice treated by connecting to said Wheel a deviceu29 which indicates the momentary rate of flow and also totals the amount of liquid passed.

I I claim:

1. Apparatusfor adding one liquid or semi-liquid to another comprising a bucket Wheel, a launder feeding the same, a float in thelaunder, brake mechanism controlled by the level of the liquid or semi-liquid in the launder and governing the bucket wheel, a conveyor for feeding the other liquid or semi-liquid geared with the bucket Wheel to move together therewith, said bucket Wheel and conveyor being arranged to commingle the liquids or semi-liquids.

2. Apparatus for adding one liquid or semi-liquid to another comprising a bucket Wheel actuated by one liquid or semiliquid, an endless conveyor geared to the bucket wheel to move there'wlth a common vessel into which the bucket wheel and conveyor discharge, a tank for supplying the second liquid or semi-liquid to the conveyor for transportation to the vessel, said tank being so raised with regard to the vessel as to make the conveyor substantially self propelling.

3. Apparatus for adding one 'liquid or semi-liquid to another comprising a bucket Wheel actuated by one liquid or semi-liquid, a conveyor for feeding the other liquid or semi-liquid and variable speed mechanism connecting thebuoket wheel and the conveyor, saidbucket Wheel and conveyor being arranged to commingle the liquids or semi-liquids.

In testimony whereof I aflix my signature;
